Sometimes, you need to find someone's IP address for different reasons. You could use it to set up a secure connection between devices, let a device join your company's network, or block a device while keeping your identity hidden.
No matter your reason, there are a few ways to get someone’s IP address. This guide shows three ways to find an IP address and what you can learn from it.
But First, What Is an IP Address, Anyway?
An IP address is like a digital fingerprint that identifies each device when it connects to the internet through the Internet Protocol (IP). It enables the internet to know where to send data when you request it. Think of it as your device's home address in the vast network of the internet. Internet Service Providers (ISPs) are the ones responsible for assigning these addresses, whether it's for your home Wi-Fi or your workplace network.
1. IPv4 and IPv6 Addresses
There are two main types of IP addresses.
IPv4 Addresses: These are the classic IP addresses you're probably familiar with: four sets of numbers separated by dots (like 192.168.1.1). They've been around for a while, but we're running out due to the explosion of internet-connected devices.
IPv6 Addresses: To solve the problem of IPv4 address scarcity, IPv6 came into play. Instead of numbers separated by dots, IPv6 addresses use a mix of numbers and letters separated by colons (like 2001:0db8:85a3:0000:0000:8a2e:0370:7334). This expanded format provides way more possible addresses, ensuring that every device can have its unique identifier.

3 Ways To Find Someone Else’s IP Address
Now, let's get back to our original discussion. There are legitimate reasons to find someone's IP address. Here are three ways to do so.
1. Use an IP Lookup Tool
If you already have someone's IP address, an IP lookup tool can help you learn more about it. Depending on the available data, you may find its approximate geographic location, internet service provider (ISP), organization, and other network details.
If you're checking your own IP address, search Google for "what is my IP address" or visit IPGeolocation.io to look up your public IP address.
Keep in mind that an IP lookup tool cannot discover someone's IP address from their name or email address alone. It provides information about an IP address you already have, and the results generally cannot establish a person's exact location or identity.
2. Check Email Headers
Email headers contain technical information about an email's delivery, including details about the mail servers involved. In some cases, they may contain an IP address associated with the sender's email system, but this is not necessarily the sender's personal IP address.
For example, Gmail lets you inspect an email's original headers:
- Open the email in Gmail.
- Click the three-dot menu next to the reply button.
- Select Show original.
- Review the headers for relevant IP addresses in the delivery information.
Keep in mind that Gmail and other email providers may omit the sender's original IP address. The addresses shown may belong to mail servers or email services instead. SPF records do not guarantee that a sender's personal IP address will appear in the headers.
Treat any IP address you find as a network clue rather than proof of someone's identity or location.
3. Command Prompt
For Windows users, finding the Command Prompt is as easy as typing "command prompt" or "cmd" into the search box on the taskbar. Mac users can open Terminal from Utilities or Spotlight. Linux users can open their terminal app.
Once you've opened the Command Prompt or Terminal, you can start typing commands. One useful command is "ipconfig (in Windows) or ifconfig (on Mac and Linux)". This command reveals all sorts of details about your network connection, including your IP address, subnet mask, and gateway.
How To Find Someone’s IP Address Through Chat
This process requires you to be interacting with the person in a live chat, video call, or VoIP session. Whether you can see the other person’s IP address depends on how the service handles the connection.
To view the network connections from your device, you can use the netstat command. Open Command Prompt and run:
netstat -an
The command lists active network connections and their local and remote endpoints. The remote IP address shown here may belong to the person you are communicating with if the connection is direct. However, many modern chat and calling platforms route traffic through their own servers, so the remote address may belong to the platform instead.
For example, services such as Slack generally use intermediary servers rather than establishing a direct connection between two users. In those cases, netstat -an will typically show the service's servers, not the other person's IP address.
A direct peer-to-peer connection is therefore required for the remote endpoint to correspond to the other participant's device.
Conclusion
Understanding how to find someone’s IP address can be valuable for various reasons, whether it's for network security or online communication. By utilizing methods like IP lookup tools, examining email headers, or using Command Prompt, you can gather essential information about IP addresses.
However, it's important to remember the limitations, such as the inability to trace an IP address directly to a specific house. Additionally, it's crucial to use these methods responsibly and legally, respecting privacy and avoiding unlawful activities.
FAQs
Discovering someone’s IP address is not illegal. It is public information utilized across the internet without legal constraints on searching for it. However, engaging in activities like tracking IP addresses for harassment or cyber offenses constitutes illegal conduct.
In some cases, an IP address may be associated with activity on social media platforms, but access to this information is generally restricted to the platform and authorized parties. Social media users typically cannot directly obtain another person’s IP address through standard messaging or chat features.
An IP grabber serves as a third-party utility generating a clickable link, facilitating the retrieval of the user’s IP address. However, employing such tools poses significant privacy and security risks.
However, don’t resort to IP grabbers for IP address information. Instead, opt for one of the three methods we discussed: IP lookup, email headers, or command prompt and ping.
Although an IP address can provide considerable information, directly pinpointing it to a specific house is virtually unattainable. ISPs assign IP addresses that are linked to general areas rather than exact physical addresses.
While you can determine the precise geolocation of an IP using an IP lookup tool like ipgeolocation.io, pinpointing a specific physical address remains elusive.
